chore: bump pydantic and fastapi

No breaking changes for us.

Pydantic is working on its own faster JSON parser, `jiter`, and 2.5.0 starts bringing this in. See https://github.com/pydantic/jiter

There are a number of other bugfixes and minor changes in this version of pydantic.

The FastAPI update is mostly internal but let's stay up to date.
